And in today's blog post we will be writing about data engineer applications. Which are basically the use cases of data engineering 1st let's see what data engineering applications mean; so basically when we have data and we have engineered it then there are several things that we can do with that data and these things that we can do with processed data are the use cases of the data engineering. For example: If we have filled our containers with the data then it's not of any good use if it is not clean and well-formed.

It will be hard sometimes but believe in yourself. You have got it. ( Rahat-Undergraduate ) Try to do good in quizzes and OHTs (One hour test or mids) cause when finals don't go well, these can help in getting good gpa which are comparatively easy then finals. ( Ayesha Munir-Undergraduate )   A few years later when you would look back at this time, GPA won't make you happy, but the memories of these 4 years will. Your career is important but so is having a good time. So work hard, party harder!

Focus on your quizzes and assignments because they are the building blocks of your Grade.. Your Good Image play some important part for favoritism points in exam....

Yes, you are absolutely right.  "John Learned from his Experience that the Task of going to the cafeteria at 1:00 P.M. on Fridays resulted in waste of time, since the cafe was closed on each Friday, so it will Perform the same on the next Friday." In the above scenario, John learned something so we can call it " John Learning ".

Marketing

I am of the opinion that everyone of us must acquire marketing skill.  Why Should We? This is because, as the world population is increasing, there is a demand for more. If we have certain talent, skill, or if we are capable of doing some task. Then, we can see there are others, who can do the same task. But, our opinion is that : We are the best in our work. So, how can we tell this to the person who needs our services? We need to devise a marketing policy, so that we and the other person gets benefit from it. Robert T. Kiyosaki describes in his book : " Rich Dad Poor Dad " that,  McDonald's is a brand that sells ham burgers. Their ham burgers might not be the best, but they might believe them to be.

The answer is their marketing policy! ( ya, along with other aspects too ) Moreover, ...

The colorful  bubble logo  is of Elasticsearch , while the redish logo is of Redis . First let's talk about Elastic search.. Elasticsearch is an open source search engine. Now, what is a search engine? Search engine is basically a website, for example: google.com, yahoo.com, bing and MSN. What we look as Google chrome, Safari or Internet Explorer is basically a Web browser. Let's say we type "www.facebook.com" in a web browser's address bar , then the web browser will take us directly to the website "facebook.com". As for search engine, if we type in its search bar , "www.facebook.com", then it will open up different links according to the search algorithm. So Elasticsearch is like a search engine. But it is different from traditional search engines. Like in most of the search engines, tables are used to store data, while elasticsearch is no schema based search engine.
